WebEight haploid ascospores are produced within each ascus. The fully formed ascospores are oval, unicellular and hyaline. When they become mature, each ascus opens explosively by a lid and the spores are shot out in a jet of liquid. Each spore under favourable conditions, germinates and forms a new mycelium.
